Kuzindikira molakwika 316 ngati chitsulo chosapanga dzimbiri 304 kumawononga kukana dzimbiri. Cholakwika ichi chimaika pachiwopsezo zida m'malo opangira zinthu za m'madzi, petrochemical, ndi chakudya, zomwe zingayambitse kulephera kwakukulu ndi kuvulala. Kusatsatira bwino zinthu kungayambitse kuswa malamulo ndi kulephera kwa ma audit. Mtengo wokonza kusokonezeka kwa alloy ndi pafupifupi $25,000–$250,000 pa chochitika chilichonse chokonzanso, nthawi yopuma, ndi zopempha za chitsimikizo.

Mavuto Ofunika Pakutsimikizira Zitsulo Zosapanga Dzimbiri 304, 316, ndi 321
304, 316, ndi 321 ali ndi mitundu yofanana, mawonekedwe ake, ndi mawonekedwe ake, zomwe zimapangitsa kuti asawonekere bwino. Kusintha kwa alloy muzinthu zomwe zili mu spectrum alloys sikungatheke kuzindikirika mpaka mavuto kapena kulephera kugwira ntchito kuonekera. Kuchuluka kwa molybdenum mu 316 (2–3%) kumafuna kuzindikira kwa elemental kuti kusiyanitse ndi 304, komwe kulibe Mo. Ma analyzer a Lonnmeter XRF amaonetsetsa kuti zipangizo zokha zomwe zili ndi makhalidwe oyenera - kukana dzimbiri kwa 316 vs 304 chitsulo chosapanga dzimbiri komanso kuchuluka kwa titaniyamu koyenera kwa 321 yotentha kwambiri.
Kusiyana AmongChitsulo Chosapanga Dzimbiri cha 304 vs 316 vs 321
Zinthu Zachilengedwe ndi Zinthu Zosiyanitsa
Chitsulo chosapanga dzimbiri cha 304 chili ndi 18–20% ya chromium, 8–10.5% ya nickel, ≤0.08% ya carbon, ndipo chilibe molybdenum ndi titaniyamu. Mosiyana ndi zimenezi, 316 yachitsulo chosapanga dzimbiri ili ndi 16–18% ya chromium, 10–14% ya nickel, ndi 2–3% ya molybdenum yofunika kwambiri, yomwe ilibe mu ma alloys ena ofanana. Kuwonjezera kwa molybdenum kumeneku kumawonjezera mwachindunji kukana kwa chloride ndi dzimbiri la mankhwala.
Chitsulo chosapanga dzimbiri cha 321, chokhala ndi 17–19% chromium, 9–12% nickel, ndi titaniyamu yokwanira (yosachepera 5xC, yoposa 0.7%), chimathandiza kuti kutentha kukhale kolimba. Titaniyamu imalumikizana ndi kaboni, zomwe zimaletsa dzimbiri pakati pa granular ndi carbide kugwa panthawi yogwira ntchito yotentha kwambiri.
Kuchuluka kwa nikeli kumawonjezeka kuchoka pa 304 kufika pa 316 kuti mankhwala azigwira bwino ntchito komanso kuti makina azigwira ntchito bwino. Chromium imakhalabe chinthu chofunikira kwambiri pakulimbana ndi dzimbiri m'magawo onse atatu. Titanium ndi chizindikiro chodziwika bwino cha 321 ndipo imatha kusiyanitsa ndi XRF analyzers.
Kugwiritsa Ntchito ndi Kuchita Bwino: Pamene Giredi Iliyonse Yasankhidwa
Chitsulo chosapanga dzimbiri cha 304 chimagwira ntchito ngati muyezo wamakampani ogulitsa zitsulo za spectrum alloys chifukwa cha mtengo wake wotsika komanso kusinthasintha kwake—chogwiritsidwa ntchito pokonza chakudya, ziwiya za kukhitchini, matanki osungiramo zinthu, ndi zida zomangamanga. Kukana kwake dzimbiri kumakwanira m'malo ovuta pang'ono.
Chitsulo chosapanga dzimbiri 316 chimagwira ntchito bwino kwambiri pazida zam'madzi, mankhwala, ndi mankhwala. Kukhalapo kwa 2–3% molybdenum ndikofunikira kwambiri posankha chitsulo chosapanga dzimbiri chabwino kwambiri cha m'madzi kapena mizere ya mafakitale yomwe imakhudzidwa ndi ma chloride, zomwe zimapangitsa kuti zikhale bwino kuposa 304 pakugwiritsa ntchito madzi amchere komanso njira zotsukira asidi.
Chitsulo chosapanga dzimbiri cha 321 chimagwiritsa ntchito kwambiri kutentha ndi ndege, ma exhaust manifolds a injini ya jet, ndi ma petrochemical heaters, omwe amalimbana kwambiri ndi kukula komanso amasunga mphamvu mpaka 900°C. Kuwonjezera kwake titanium kumatsimikizira kudalirika pakasinthasintha kutentha mobwerezabwereza, kuchepetsa chiopsezo cha carbide kugwa pambuyo powotcherera.

Momwe XRF Analyzers Imathandizira Kuzindikira Mwachangu, Kodalirika kwa Alloy
Mfundo Zogwirira Ntchito zaLonnmeter Ukadaulo wa XRF (X-ray Fluorescence)
Ofufuza a XRF amatulutsa ma X-ray amphamvu kwambiri pa zitsanzo zachitsulo chosapanga dzimbiri, zomwe zimapangitsa maatomu kutulutsa ma elekitironi amkati mwa chipolopolo. Malo omwe amapezeka amadzazidwa ndi ma elekitironi ochokera ku mphamvu zapamwamba, kutulutsa ma X-ray achiwiri omwe ali ndi mawonekedwe a chinthu chilichonse. Ofufuza amayesa mpweya umenewu, poyesa kuchuluka kwa ma elementi a ma alloys monga 304, 316, ndi 321 osapanga dzimbiri. XRF imalola kuzindikira mwachangu, kosawononga, kupereka ziwerengero mumasekondi 30.
Mtengo Wapadera wa XRF Posiyanitsa 304, 316, ndi 321
XRF imasiyanitsa bwino magiredi osapanga dzimbiri mu alloy spectrum. Kuyerekeza kwa 316 stainless steel ndi 304 stainless steel kumadalira kuzindikira molybdenum—316 ili ndi 2–3% Mo, yomwe XRF imazindikira nthawi yomweyo. 321 grade imasiyanitsidwa ndi XRF poyesa kuchuluka kwa titaniyamu pamwamba pa 0.3%. Kuzindikira kuchuluka kumapereka zotsatira zomwe zingatheke: ma ppm values, pass/fail classification, ndi alloy library matching.
Chowunikira cha Lonnmeter XRF Kuzindikira Chitsulo Chosapanga Dzimbiri ndi Spectrum Alloy
Zinthu Zazikulu ndi Mafotokozedwe Aukadaulo
Chowunikira cha Lonnmeter XRF chimapereka mphamvu ya 0–50 kV, ukadaulo wa Silicon Drift Detector, ndi liwiro la masekondi 30. Kulondola kumafika ±0.01% pazinthu zofunika, kukonza kuzindikira kwa spectrum alloy. Chipangizochi chimaphatikiza mawonekedwe a touchscreen, malaibulale ophatikizidwa achitsulo chosapanga dzimbiri, komanso kuyerekeza kwa spectra nthawi yeniyeni. Kuchuluka kwa batri kumathandizira mpaka maola 8 ogwira ntchito mosalekeza.
Kuphatikiza ndi Zolinga za Kuyang'anira Ubwino ndi Zopanga
Lonnmeter imagwirizana ndi machitidwe oyang'anira khalidwe kuti zitsimikizire bwino zinthu panthawi yosungiramo katundu, kupanga, ndi kuwunika komaliza. Imaletsa kutumiza zinthu zosakanikirana, kuchepetsa ndalama zogwirira ntchito komanso kuchedwa kupanga. Kutulutsa deta kumathandizira kukonza kosalekeza ndi zofunikira zowunikira ndi tsiku lokha, malo, ndi kutsatira batch. Zosankha zolembera zimatsimikizira kuti zinthuzo zitha kutsatiridwa mkati mwa ma alloys a spectrum omwe amaperekedwa ndi ogulitsa zitsulo zosapanga dzimbiri komanso ogulitsa zitsulo.
Kupempha Mtengo wa Lonnmeter XRF Analyzer
Makasitomala amasankha kusintha kwa laibulale ya kalasi ndi kukonza mautumiki. Chithandizo chimaphatikizapo maphunziro, chitsimikizo, ndi njira zosamalira kuti zigwiritsidwe ntchito.
Mafunso Ofunsidwa Kawirikawiri (Mafunso Ofunsidwa Kawirikawiri)
Kodi kusiyana kwakukulu pakati pa chitsulo chosapanga dzimbiri cha 304 ndi 316 ndi kotani?
316 ili ndi 2–3% ya molybdenum, yomwe imakweza kukana kwa chloride ndi mankhwala kupitirira madigiri 304. 304 imakhalabe yotetezeka ku zinyalala m'malo a m'nyanja ndi m'malo okhala ndi mchere. 316 ndi yabwino kwambiri chifukwa cha madzi amchere komanso mankhwala oopsa, pomwe 304 ndi yofala kwambiri pokonza chakudya ndi zipangizo zapakhomo.
Nchifukwa chiyani molybdenum ndi yofunika mu chitsulo chosapanga dzimbiri cha 316?
Molybdenum imapereka mphamvu yolimbana ndi madzi amchere, ma acid, ndi mankhwala a mafakitale. Kuwonjezera kumeneku kumaletsa dzimbiri la m'ming'alu ndi ming'alu, zomwe zimapangitsa kuti 316 ikhale yoyenera kugwiritsa ntchito ma spectrum alloys omwe amapezeka m'madzi ndi m'malo osungiramo mankhwala.
Ndi mafakitale ati omwe amapindula kwambiri ndi zowunikira za XRF alloy zonyamulika?
Magawo a petrochemical, amlengalenga, opanga, ndi omanga amagwiritsa ntchito ma XRF analyzers kuti ayerekezere bwino komanso molondola, kuchepetsa chiopsezo pamitundu yonse ya alloy yachitsulo chosapanga dzimbiri.
